A bar serving as a regulating member of a motor drive device has a first projecting piece that is formed so as to curve downwards after extending in the horizontal direction from a top part thereof, and a second projecting piece that projects downwards from a bottom part thereof, and by the first projecting piece being placed in an upper insertion part and the second projecting piece being placed in a lower insertion part, a fan unit is fixed in a mounting hole of a flange.
Description
- This application is based on and claims the benefit of priority from Japanese Patent Application No. 2016-109036, filed on 31 May 2016, the content of which is incorporated herein by reference.
- The present invention relates to a motor drive device equipped with a fan unit.
- A heat sink for heat dissipation is installed to a motor drive device mounted on a power panel. Furthermore, a fan motor is installed to the heat sink, and enhances the cooling effect. The fan motor used in a machine tool is used in an environment in which cutting oil mist and fine particles are whirling, whereby the lifespan thereof may decline by use over a long period; therefore, it is necessary to replace and inspect periodically. Then, the fan motor for heat-sink cooling of a motor drive device is commonly positioned on the back surface side of the power panel. However, the back surface side of a power panel is often adjacent to a wall or the like, and accessing the fan motor of a motor drive device from the back surface side of the power panel is difficult in reality. For that reason, in the conventional technology, it has been necessary to remove the motor drive device from the power panel in order to replace or inspect the fan motor. In the case of removing the motor drive device from the power panel in this way, not only are the working hours extended, but there is a possibility of a wiring mistake occurring when re-installing the motor drive device to the power panel. Patent Document 1 is a patent made by taking account of such a situation, and relates to a motor drive device that enables the fan motor to be replaces or inspected without removing the motor drive device from the power panel. Patent Document 1 describes, in relation to an inverter device (motor drive device), a structure which seals an opening of a flange by fixing a fixing member that fixes the fan unit to the flange which is installed to a control panel.
- Patent Document 1: Japanese Patent No. 4734299
- The power panel and interior of the motor drive device are preferably separated from the exterior. For example, with a motor drive device used in a location at which performing cutting, there is concern over inviting damage to the power element inside the motor drive device or the electrical components on the printed board, if air containing cutting fluid (cutting fluid mist) penetrates to the interior of the power panel. In this regard, Patent Document 1 prevents the infiltration of foreign substances or dirty air to the interior by way of closing the opening of the flange by way of the fan fixing member. However, the fixing of the fan fixing member to the flange has been performed by fastening screws to a plurality of locations above and below the fan fixing member; therefore, it has been necessary to remove all of the screws at the plurality of locations above and below upon a maintenance operation on the fan unit. Depending on the case, work space is necessary for removing the screws using a tool such as a screw driver, and maintenance operation on the fan unit may also not be performed unless removing other components. In this way, there has been margin for improvement from the viewpoint of an increase in operability in the conventional technology.

FIG. 1 is a perspective view of a motor drive device 1 according to a first embodiment of the present invention, showing a state in which afan unit 50 is removed from aflange 20.FIG. 2 is a perspective view of the motor drive device 1 according to the first embodiment of the present invention, showing a state in which thefan unit 50 is mounted to theflange 20. It should be noted that, in the drawings, an aspect viewing the state cutting off a part of a panel surface of apower panel 5 from an interior side is shown. - In the
power panel 5, anopening 6 that is in communication with an external space on a back side thereof is formed, and theflange 20 is fixed to a position corresponding to thisopening 6. - The
flange 20 has aheat sink 12 coupled to a back face thereof. Anopening 26 for retaining apower element 11 at the inside and amounting hole 21 for mounting thefan unit 50 are formed in theflange 20. In the present embodiment, theheat sink 12 is fixed in a state contacted by a portion of the circumference of theopening 26 at the back face (surface on external side) of theflange 20. Then, thepower element 11 is fixed to the surface (face on interior side) of theheat sink 12, and thepower element 11 is positioned on an interior side of thepower panel 5. - The
mounting hole 21 to which thefan unit 50 is mounted is formed in a top part of theflange 20. Themounting hole 21 communicates the interior and exterior of thepower panel 5. For the mountinghole 21 of the present embodiment, the position thereof becomes above thepower element 11 andheat sink 12. In addition, screw holes 23 are formed in the corners on the upper side of the surface of theflange 20. The screw holes 23 are formed at a total of two locations at the upper right and upper left of the mountinghole 21 in a front view. - A
fan unit hook 22 is provided below the mountinghole 21 in the surface of theflange 20, and above thepower element 11. Thefan unit hook 22 is a regulating member that regulates movement from the mountinghole 21 towards a distancing direction by locking thefan unit 50. -
FIG. 3 is a perspective view of thefan unit 50 of the first embodiment. Thefan unit 50 is configured to be detachable relative to theflange 20 mounted to thepower panel 5. Thefan unit 50 includes afan 51, afan fixing member 52, and packing 55 as principal configurations. - The
fan 51 is a cooling device for cooling theheat sink 12. As shown inFIG. 2 , thefan 51 is positioned at a cooling position to cool theheat sink 12 when thefan unit 50 is mounted to the mountinghole 21. The cooling position of thefan 51 of the present embodiment becomes above theheat sink 12. - The
fan fixing member 52 functions as a support part that supports thefan 51, as well as functioning as a cover that blocks the mountinghole 21 of theflange 20. Thefan fixing member 52 of the present embodiment includes acover 53 that covers the mountinghole 21, and asupport part 54 that extends in a horizontal direction from the back side of thecover 53 and supports thefan 51. In addition, an insertion holes 56 corresponding to the position of the screw holes 23 are formed at two locations in thecover 53. - The packing 55 is arranged at the surface on the outer side of the
cover 53, and is an elastic member formed in a rectangular frame shape according to the shape of the mountinghole 21. When thefan unit 50 is mounted to the mountinghole 21, the packing 55 elastically deforms and the gap between thecover 53 andflange 20 is filled. -
FIG. 4 is a side view showing a state in which thefan unit 50 of the first embodiment is fixed to theflange 20. Thefan unit hook 22 is formed in an L-shape bending upwards, after protruding in the horizontal direction from the surface of theflange 20. Afitting recess 25 for fitting thefan unit 50 is formed by an L-shaped curved portion of thefan unit hook 22 and the surface of theflange 20. - Next, a step of mounting the
fan unit 50 of the first embodiment to the mountinghole 21 will be explained. First, as shown inFIG. 1 , a portion of thefan 51 of thefan unit 50 is placed into the mountinghole 21. Next, as shown inFIG. 4 , a bottom end of thecover 53 is inserted into thefitting recess 25 of thefan unit hook 22, and thefan 51 is arranged at the cooling position. By thecover 53 inserting into thefitting recess 25 of thefan unit hook 22, the movement in a distancing direction from the mountinghole 21 of thefan unit 50 is regulated, and enters a state in which thefan unit 50 is retained in the mountinghole 21. In a state in which thefan unit 50 is retained in the mountinghole 21, thescrews 60 pass through the insertion holes 56 at two locations and are threaded together with the screw holes 23 of theflange 20. A portion corresponding to the bottom side of thecover 53 is fixed to thefan unit hook 22 over the longitudinal direction, and a portion corresponding to the top side of thecover 53 is fixed by thescrews 60 at two locations on both sides, whereby thefan unit 50 is fixed with good adhesion to the mountinghole 21. For maintenance operations, etc., when thefan unit 50 is removed from theflange 20, it is performed in the reverse order to the operation of mounting. In other words, thescrews 60 are removed, the engaging between thecover 53 of thefan unit 50 and thefan unit hook 22 is released, and thefan unit 50 is drawn out from the mountinghole 21. - According to the motor drive device 1 of the first embodiment explained above, the following such effects are exerted. More specifically, the motor drive device 1 includes a
flange 20 mounted at a position corresponding to theopening 6 formed in thepower panel 5, and in which a mountinghole 21 is formed that is in communication with the back side (outer side) of thepower panel 5, aheat sink 12 that is supported by theflange 20 at a back side of thepower panel 5, afan unit 50 having afan 51 that can be arranged at a cooling position to cool theheat sink 12 on a back side of thepower panel 5 through the mountinghole 21 and afan fixing member 52 that supports thefan 51 at the cooling position and blocks the mountinghole 21, and afan unit hook 22 that is arranged at theflange 20 and regulates movement of thefan fixing member 52 in a direction distancing from the mountinghole 21. Thefan unit hook 22 has afitting recess 25 that fits in a vertical direction with thefan fixing member 52, the insertion holes 56 for insertingscrews 60 are formed in thefan fixing member 52, and thefan unit 50 is fixed to theflange 20 by thescrews 60 being fastened to theflange 20 through the insertion holes 56 in a state in which thefan fixing member 52 fits in thefitting recess 25. - Since it is sufficient for the insertion holes 56 formed in the
cover 53 to only be at the top part, it is thereby possible to shorten the length in the vertical direction of thecover 53 compared to a case of forming the insertion holes 56 above and below at two locations. In addition, since it is sufficient for the space at a front side of theflange 20 required in order to fasten thescrews 60 by a screw driver to only be a portion in which the threadedholes 23 are formed, it is possible to raise the degrees of freedom in arrangement location and design. In addition, by supporting the bottom end of thecover 53 by thefan unit hook 22, thefan unit 50 is retained at the position thereof upon the position in the vertical direction of thefan unit 50 being decided; therefore, an operator can perform the fastening operation of thescrew 60 using both hands. Compared the conventional technology which fixes thefan unit 50 to theflange 20 using only thescrews 60, it is possible to reduce the number ofscrews 60, and thus shorten of the working hours consumed in the fastening operation can also be realized. - Next, another embodiment in which the structure mounting the fan unit to the flange differs from the first embodiment will be explained. It should be noted that, in the following explanation, the same reference symbols are assigned for configurations similar to configurations which have already been explained, and explanations thereof may be omitted.

FIG. 5 is a perspective view of amotor drive device 201 according to a second embodiment of the present invention, showing a state in which thefan unit 50 is removed from aflange 220.FIG. 6 is a side view showing a state in which thefan unit 50 of the second embodiment is mounted to theflange 220. - As shown in
FIG. 5 , aflange recess 221 in which thecover 53 of thefan unit 50 is accommodated is formed in theflange 220 possessed by themotor drive device 201 of the second embodiment. The shape of thecover 53 of thefan unit 50 and theflange recess 221 correspond, and the mountinghole 21 enters a closed state by thecover 53 settling in theflange recess 221. - The
motor drive device 201 of the second embodiment includes aslide member 230 for fixing thefan unit 50. Theslide member 230 is a plate of laterally-long rectangular shape. Aninsertion hole 256 corresponding to thescrew hole 23 of theflange 220 is formed in the corners on both upper sides of the surface of theslide member 230, respectively. It should be noted that thefan unit 50 of the second embodiment is a structure in which the insertion holes 56 that were formed in thecover 53 of the first embodiment are not formed in thecover 53, and thefan unit 50 is not directly fastened by thescrews 60. - A
slide hook 222 is provided below therecess flange 221 in the surface of theflange 220. Theslide hook 222 is formed un an L shape that bends upwards, after projecting in the horizontal direction from the surface of theflange 20. Afitting recess 225 for fitting theslide member 230 is formed by the L-shaped curved portion of theslide hook 222 and the surface of theflange 220. - Next, the process of mounting the
fan unit 50 of the second embodiment to the mountinghole 21 will be explained. First, as shown inFIG. 5 , the portion of thefan 51 of thefan unit 50 is put into the mountinghole 21. The packing 55 also elastically deforms uniformly, without elastically deforming only the upper side or lower side, in the course of thefan unit 50 being inserted in the horizontal direction to the mountinghole 21, and the mountinghole 21 is blocked in a state keeping high sealability. - As shown in
FIG. 6 , by thecover 53 settling in theflange recess 221, the surface of theflange 220 and the surface of thecover 53 become substantially flush. In this state, theslide member 230 is put into thefitting recess 225 of theslide hook 22 from above. In a state putting theslide member 230 in thefitting recess 225, thescrew 60 is screwed together with thescrew hole 23 of theflange 220 through theinsertion hole 256. Theslide member 230 is thereby fixed at a position regulating the movement of thefan unit 50 in a direction distancing from the mountinghole 21 by the front of theflange 220. For maintenance operations, etc., when thefan unit 50 is removed from theflange 220, it is performed in the reverse order to the operation of mounting. - According to the
motor drive device 201 of the second embodiment explained above, the following such effects are exerted. In other words, themotor drive device 201 further includes theslide member 230 that is arranged on theflange 220, and regulates the movement of thefan fixing member 52 in a direction distancing from the mountinghole 21. Theslide hook 222 that fits in the end on one side of theslide member 23 is formed at theflange 220, and theslide member 230 is formed in a plate shape, as well as theinsertion hole 256 through which thescrew 60 is inserted being formed in the end on the opposite side to the side fitting with theslide hook 222. In a state in which theslide member 230 is fitting with theslide hook 222, thescrew 60 is fastened to theflange 220 through theinsertion hole 256, and thefan unit 50 is fixed to theflange 220. - Since the
insertion hole 56 formed in thecover 53 is thereby no longer necessary, it is possible to shorten the length in the vertical direction of thecover 53 compared to the case of forming theinsertion hole 56. In addition, since it is sufficient for the space on the front side of theflange 220 required in order to fasten thescrews 60 by a screw driver to only be a portion in which thescrew hole 23 are formed, it is possible to raise the degrees of freedom in arrangement locations and design. Since it is possible to fix the position of thefan unit 50 by theslide member 230 having the end on one side fitted in theslide hook 222, it is possible to decrease the number ofscrews 60 compared to the conventional technology which has fixed thefan unit 50 to theflange 20 using thescrews 60, and thus shortening of the working hours consumed in the fastening operation can also be realized. In addition, in a configuration including the packing 55 as in the present embodiment, thefan unit 50 is inserted in the horizontal direction, and thefan unit 60 is pressed at the surface by theslide member 230 formed in a plate shape; therefore, it is possible to uniformly elastically deform the packing 55, and thus it is possible to further raise the sealability. - Next, a

FIG. 7 , aflange recess 321 accommodating thecover 53 is formed in theflange 320, similarly to the second embodiment. Arotation member 330 serving as a regulating member that regulates the movement of thefan unit 50 in a direction distancing from the mountinghole 21 is arranged below theflange recess 321 in the surface of theflange 320. - The
rotation member 330 is a plate of laterally-long rectangular shape, and an end on one side is supported by theflange 320 via arotary shaft 331. In the present embodiment, therotation member 330 is rotatably fitted to therotary shaft 331 provided to theflange 320. - The
rotation member 330 is configured to be rotatable between a distanced position when thefan unit 50 is removed from the mountinghole 21, and a regulated position when thefan unit 50 is mounted to the mountinghole 21. The distanced position of therotation member 330 is set to a position at which not blocking the mountinghole 21, and not interfering with the insertion direction of thefan unit 50. For example, as shown inFIG. 7 , the leading end of therotation member 330 becomes rotatable until a state facing the horizontal direction. It should be noted that it is not limited to the state shown inFIG. 7 , and it may configure a state in which the leading end of therotation member 330 is facing down as the distanced position. - The regulated position is a position at which a planar portion on one side of the
rotation member 330 opposes the surface of thecover 53. As shown inFIG. 8 , a state in which the leading end of therotation member 330 faces upwards is the regulated position. In addition, as shown inFIG. 7 , insertion holes 356 corresponding to the positions of the screw holes 23 in the state that is the regulated position are formed at two locations in therotation member 330. - Next, the process of mounting the
fan unit 50 of the third embodiment to the mountinghole 21 will be explained. First, as shown inFIG. 7 , a portion of thefan 51 of thefan unit 50 is put in the mountinghole 21. Next, as shown inFIG. 8 , therotation member 330 is made to rotate from the distanced position to the regulated position. Thescrews 60 are screwed into the screw holes 23 of theflange 220 through the insertion holes 356 in a state in which therotation member 330 is at the regulated position. Therotation member 330 is thereby fixed at the regulated position regulating the movement of thefan unit 50 in a direction distancing from the mountinghole 21. For maintenance operations, etc., when thefan unit 50 is removed from theflange 320, it is performed in the reverse order to the operation of mounting. - According to the
motor drive device 301 of the third embodiment explained above, the following such effects are exerted. Specifically, therotation member 330 serving as the regulating member of themotor drive device 301 is supported by theflange 320 to be rotatable between the regulated position at which an end on one side contacts thefan fixing member 52, and a distanced position distancing from thefan fixing member 52, as well as the insertion holes 356 through which thescrews 60 are inserted being formed in an end on an opposite side to the side rotatably supported In a state in which therotation member 330 is at the regulated position, thescrews 60 are fastened to theflange 320 through the insertion holes 356, and thefan unit 50 is fixed to theflange 320. - Since the insertion holes 56 formed in the
cover 53 are thereby no longer necessary, it is possible to shorten the length in the vertical direction of thecover 53 compared to a case of forming the insertion holes 56. In addition, since it is sufficient for the space on the front side of theflange 320 required in order to fasten thescrews 60 by a screw driver to only be a portion in which the screw holes 23 are formed, it is possible to raise the degrees of freedom in arrangement locations and design. Since it is possible to fix the position of thefan unit 50 by simply moving therotation member 330 to the regulated position, it is possible to decrease the number ofscrews 60 compared to the conventional technology which has fixed thefan unit 50 to theflange 20 using thescrews 60, and thus shortening of the working hours consumed in the fastening operation can also be realized. In addition, since therotation member 330 is being mounted to theflange 320, there is no requirement to remove as a separate component, or concern over losing by dropping, and thus operability is good. In addition, in a configuration including the packing 55 as in the present embodiment, thefan unit 50 is inserted in the horizontal direction, and thefan unit 50 is pressed at the surface by therotation member 330 formed in a plate shape; therefore, it is possible to uniformly elastically deform the packing 55, and thus it is possible to further raise the sealability. - Next, a
motor drive device 401 of the fourth embodiment will be explained.FIG. 9 is a side view showing a state in which thefan unit 50 of the fourth embodiment is fixed to aflange 420.

fitting part 435 is formed at a leading end of therotation member 430. In addition, afitting recess 436 corresponding to thefitting part 435 of therotation member 430 is formed in the upper face of theflange 420. By rotating therotation member 430 until the regulated position in a state inserting thefan unit 50 in the mountinghole 21, and putting the leading end of thefitting part 435 of therotation member 430 in thefitting recess 436, thefan unit 50 is fixed to the mountinghole 21. When performing a maintenance operation, after releasing fitting of thefitting part 435 andfitting recess 436, therotation member 430 is made to move in the distancing direction and thefan unit 50 is drawn out from the mountinghole 21. - According to the
motor drive device 401 of the fourth embodiment explained above, the following such effects are exerted. More specifically, therotation member 430 serving as the regulating member of themotor drive device 401 is supported by theflange 420 to be rotatable between the regulating position contacting thefan fixing member 52 and the distancing position that distances from thefan fixing member 52, as well as thefitting part 435 that fits in thefitting recess 436 in the top part of theflange 420 being formed in the end on the opposite side to the side supported to be rotatable. Thefitting part 435 fits in thefitting recess 436 in the top part of theflange 420 in a state in which therotation member 430 is at the regulating position, whereby thefan unit 50 is fixed to theflange 420. - Since the
insertion hole 56 formed in thecover 53 is no longer necessary, it is thereby possible to shorten the length in the vertical direction of thecover 53 compared to a case of forming theinsertion hole 56. It is possible to fix thefan unit 50 by simply causing therotation member 430 to move to the regulating position, and fitting thefitting part 435 in theflange 420, and it is not necessary to perform a fastening operation of thescrews 60, and thus shortening of the working hours can also be realized. Moreover, in addition to therotation member 430 being mounted to theflange 320, since thescrews 60 are also not necessary, there is no requirement to remove as a separate component, or concern over losing by dropping, and thus operability is good. In addition, in a configuration including the packing 55 as in the present embodiment, thefan unit 50 is inserted in the horizontal direction, and thefan unit 50 is pressed at the surface by therotation member 430 formed in a plate shape; therefore, it is possible to uniformly elastically deform the packing 55, and thus it is possible to further raise the sealability. - Next, a
